Purpose - This study proposes the impact of the US and Korean economic policy uncertainty on macroeconomy, and its effect on Korea. The economic policy uncertainty index of the US and Korea is used to represent the economic policy uncertainty on Korean economy. Research design, data, and methodology - In this paper, we collect the eight variables to find out the interrelationship among the US and Korean economic policy uncertainty index of the US and macroeconomic indicators during 1990 to 2016, and use Vector Error Correction Model. Result - The distribution industry stock index in Korea is influenced by the economic policy uncertainty index of the US rather than of Korea. All variables are related negatively to the economic policy uncertainty index of the US and Korea from Vector Error Correction Model. This study shows that the economic policy uncertainty index of the US and Korea has the dynamic relationships on the Korean economy. Conclusions - A higher economic policy uncertainty shows a greater economy recession of a country. Finally, the economic policy uncertainty of the Korea has an intensive impact on Korea economy. Particularly, the economic policy uncertainty of the US has a strong impact on distribution industry stock market in Korea.

Purpose: The study was to analyze clinical outcomes and risk factors of for complications associated with the hip fracture surgery in the elderly before and after interdisciplinary treatment. Methods: A retrospective method was used to investigate the general and therapeutic characteristics, frequency of complications and clinical outcomes. The subjects of the study were 553 patients who underwent hip fracture surgery from January, 2009 to December, 2014. Results: The interdisciplinary group was older and less likely to walk independently even before the fracture than a usual care group. The incidence of complications was higher in the interdisciplinary group than the usual care group. The prevalence of complications in both groups was 66.5%. Multivariate logistic regression analysis showsed that the risk factors for complications of hip fracture surgery were as follows: advanced age, stroke, Parkinson disease, time interval from emergency room to operation, pre & post ambulatory status, American Society of Anesthesiologists (ASA) classification quality of postop intensive care unit (ICU) care and foley indwelling. Conclusion: This study has implications in that it recognized the necessity for interdisciplinary treatment and provided the basic base data for nursing intervention of the elderly patients who underwent hip fracture surgery.

Purpose : This study aimed to explore and describe good nursing experiences of patients with cancer. Methods : Data were collected using individual in-depth interviews with 15 males and 8 females who were hospitalized in a Korean cancer hospital. The transcribed script was analyzed using Colaizzi's phenomenological method. Results : As a result, three theme clusters and nine themes were identified. The three theme clusters were as follows: "being kind and expert in every step along the cancer care trajectory," "taking an omnipotent mediator role supporting patients' well-being," and "providing professional care touching patients' mind and body." Three themes were assigned to each cluster to illustrate the given phenomena. Conclusion : Cancer patients wanted considerate understanding and sincere care from nurses while they experienced physical and emotional suffering owing to the cancer, treatment trajectory, and hospital system. To improve the quality of nursing care for cancer patients, patient-centered care combined with nurses' expertise in oncology care must be provided based on the insights from our study's findings.

Steel industry is the most capital intensive and the largest energy consuming industry, which operate huge and complex facilities to supply various steel products as the primary materials to almost every manufacturing industry Major steel products are hot-rolled and cold-rolled coils, plates, and wires that are produced through molten iron making, molten steel making, casting, and rolling. Each process runs in batch between setups and the specifications or bach are different with each other High energy consuming and heavy material handling require careful synchronization or processes, as well. Considering the synchronization or processes, the lot planning and scheduling problem in the integrated steelmaking process rovers the roll grouping with given casts. the sequencing or rolls over time, and the machine assignment and time scheduling or charges and casts. The problem is investigated by dividing it into two cases whether single or parallel machines at the molten steel making and the continuous casting processes. Problem descriptions and solution approaches or each instance are introduced. To test their performance and conformity, implementation or the algorithms and numerical experiments are carried out with real world and constructed data sets.

The objective of this study was to develop a simple, less time-consuming and accurate sampling technique based on solid-phase sorption with activated carbon as the sorbents. The results from solid-phase sorption techniques were compared to that from a conventional solvent impinger-based technique to confirm the efficacy of the proposed method. The laboratory results indicated that the solid-phase sorption method was suitable for the determination of siloxanes as the measured concentrations were similar to that from a solvent impinge method. The data from solid-phase sorption method showed excellent recovery and reproducibility while the sampling was less labor intensive and less time consuming than the solvent impinge method. Following the laboratory tests, the solid-phase sorption technique was successfully applied to sampling biogas from a field site. This study shows that the activated carbon-based solid-phase sorption can be a reliable and less time-consuming option for the sampling and collection of siloxanes under various different landfill conditions.

Arterial oxygen saturation ($SpO_2$) monitoring for newborns requires special attention in neonatal intensive care units (NICUs). Newborns have very low photo-plethysmogram (PPG) amplitudes and their body movements are difficult to contain. Hardware design and its associated signal processing algorithms should be robust enough so that faulty measurements can be avoided. In this study, improved designs were implemented to deal with low perfusion, motion artifact, and the influence of ambient light. Dynamic range was increased by using different LED intensities and a feedback system. To minimize the effects of motion artifact and to discard other unqualified data, four additional algorithms were used, which were based on dual-trace detection, continuity of DC level, morphology of PPG, and simultaneity check of $SpO_2$. Our $SpO_2$ system was tested with newborns with normal respiration in the NICU. Our system provided fast, real-time responses and 100% artifact detection was accomplished under 84% of $SpO_2$.
